GAS-PRODUCER.

SPECIFICATION forming part of Letters Patent No. 780,090, dated January 17, 1905.

Application filed April 29, 1904'. Serial No. 205,597.

To all whmn it may concern:

Be it known that we, WILLIAM JOHN Onoss- LEY, of Crossley Brothers,Lin1ited, ()penshaw, Manchester, and THOMAS RIGBY, of 15 West Bank, Higher Openshaw, Manchester, in the county of Lancaster, England, engineers, have invented certain new and useful Improvements in Gas-Producers, of which the following is a specification.

Our invention has for its object the better and more economical working and greater efiiciency of those gas-producers which generate gas suitable for power and heating purposes, and in order that our invention maybe fully understood and readily carried into effect we will describe the same with reference to the accompanying sheets of drawings.

Figure 1 is a part sectional elevation of our improved gas-producer. Fig. 2 is a sectional elevation of the same.

The improved producer consists of a suitable shell, such as the metal cylinder 1, (either with or without the external superheatingjacket 2,) suitably lined with fire-bricks or other refractory materials 3 and inclosed at the top. The lower portion of the producer is mounted on a circular angle-plate' i, preferably built up of and arranged in segments of a circle, which are in turn carried on small piers or slabs of concrete 5 or brickwork at the floor-level. The horizontal sides of the angle-plates 4. form a support for the lircbrick lining 3, and their vertical sides dip into water contained in the spaces 6 between the concrete piers and the bottom. The lower portion of the gas-produceris thereby effectually sealed, the water-lutes being arranged with sloping sides 7 to provide easy access for the purpose of raking ashesfrom the bottom. In the center of the bottom portion of the producer is mounted a vertical cylinder 8, on the top of which is formed a ball-race, and the balls 9 in turn support a rotary cone fire-grate 10. The under side of the baseplate of the cone is provided with bevel-teeth 11, into which gear the teeth of a bevel-pinion 12, mounted on a shaft 13, running at right angles to the vertical center line of the per inside portion of one of two horizontal and of course rotate with the cone 10 and its,

base-plate, the ball-bearing 9 insuring easy rotation. The vertical cylinder 8, supporting the tire-grate, is in turn either supported on the raised concrete or brickwork foundation 5 or is carried by pillars from the bed of the producer, and if the latter then the lower portion of the cylinder is sealed in the water. The opposite horizontal pipes 14: are one or both of them used to transmit the superheated air or air and steam blast from the annular space between the shells 1 and 2 to the lire-grate, and suitable cleaning-doors 17 are provided at their outer ends. The pipes 14; may be of any suitable shape, but are preferably of the section shown in Fig. 1 or of such other section that the descent of the burned ashes is facilitated down the conical fire-grate 10 into the water-lutes 6.

The weight of the fuel mass in the present arrangement is only partly carried by the conical lire-grate 10, whereas in previous arrangements all the weight has been carried by the fire-grate and made it extremely diflicult, if not impossible, to move it in the ease of large producers. In this case only part of the weight of the fuel is on the lire-grate 10, the

remainder being carried by the bottom of the producer, and as ashes are removed from the water-lutes 6 the fuel, with the help of the rotary motion of the grate, gradually and evenly into the center of the fuel-bed is insured. The cone 10 being symmetrical and placed centrally causes the air-blast to be distributed equally over a large area. whereby gas of a uniform and high calorific value is continually produced and the fuel is thoroughly consumed.

The gas generated is led away from the producer through the outlet-pipe 19. The fuel is fed into the producer through a centrallyplaced feeding-hopper 20 at the top of the apparatus, and ball-covered poke-holes 21 are provided at the top of the producer for inspection and poking purposes.

The shaft 13 may be rotated intermittingly by hand or slowly and continuously by power in order to rotate the conical fire-grate intermittingly or continuously, as desired.

By placing the shaft 13 in the horizontal air-supply 14 and the gears 11 and 12 below the fire-grate 10 the gearing is protected by the air and steam from the fierce heat of the fire to which it would otherwise be exposed.

What we claim, and desire to secure by Letters Patent of the United States, is

In combination in a gas-producer a vertical cylinder of but half the diameter of the producer mounted concentrically within the producer on a concrete bed or other suitable foundation, a ball-race on the top of the cylinder, a rotary conical perforated fire-grate mounted on the ball-race, horizontal pipes for the supply of air and steam to the interior of the cylinder, bevel-teeth on the base-plate of the cone, and a bevel-pinion gearing therewith and fixed on a shaft passing along one of the horizontal air-pipes and terminating outside the producer all substantially as and for the purposes herein set forth.

In witness whereof we have hereunto set our hands in presence of two witnesses.
